Stiff and painful joints | Apple peel extract supplementation increases flexibility
The peels of apples contain substances with tumor-inhibiting properties, we wrote recently. The same substances may also have a positive effect on stiff and painful joints, according to a small and exploratory human study.
Study
The extract used by the researchers is marketed as AppleBoost and AppleActiv. It is a product of the Canadian Leahy Orchards, [applesnax.com] a producer of, among other things, apple sauce that funded the study.
Some of the subjects took painkillers during the study, but did not change the dosage of their medication during the experiment. Before, during and immediately after supplementation, the researchers measured the subjects' freedom of movement [range of motion; ROM]. They wanted to know whether the supplement made the joints more flexible, allowing the subjects to move more freely.
There was no placebo group.
Results
The subjects suffered less from pain, and the activity of free radicals decreased in their blood.
In a series of in vitro experiments, the researchers were able to find out that the active substances in the supplement could penetrate cells, where they reduced the free radical effect. They also saw that the apple peel supplement inhibited the formation of inflammatory factors from fatty acids.
Conclusion
"Further studies are warranted, and should include a placebo-controlled dose study to evaluate at which daily dose improvements in joint function and antioxidant status can be detected, and should incorporate tracking of diet and exercise, as well as frequency of additional adjunct therapies."
"Future studies may also include assessment of joint health support in younger populations, including athletes."
